The co-pilot who delibrately crashed the Germanwings A320 jet in the French Alps had researched suicide and the security of cockpit doors in the week before the crash. Prosecutors said internet searches made on the tablet found in his Dusseldorf flat included “ways to commit suicide” and “cockpit doors and their security provisions.” Spokesman Rauf Herrenbrueck said: “He concerned himself on one hand with medical treatment methods, on the other hand with types and ways of going about suicide. In addition, on at least one day, Lubitz concerned himself with search terms about cockpit doors and their security precautions.” Meanwhile, the second flight data recorder from the plane has been found, the Marsielle prosecutor said. The second “black box” recovered is the flight data recorder with readings for nearly every instrument seen as vital to the investigation into the crash. If it is not too badly damaged, investigators will hope to retrieve technical information on the time of radio transmissions and the plane’s acceleration, airspeed, altitude and direction.
